A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
Background: Electrocardiography (ECG) is commonly used in psychological research and clinical practice; however, ECG machines are impracticable. This study cross-validates two wireless alternatives (Empatica E4 and polar H10) and assesses whether they agree with the golden standard. The monitors are normed to the REFA. To assess the validity of these devices, participants performed different tasks. Methods: An within-subject experiment was conducted. Participants (N= 28) performed a resting, physical and mental task (Stroop task and emotional Stroop) while being attached to the three devices. Results: The polar was highly agreeable and correlated with the REFA. The devices did not find a difference between the Stroop tasks. The devices found a difference between the physical and resting task. Limitations: The Empatica E4 did not collect enough data points to be accurately compared. Conclusion: The polar is highly agreeable with the REFA and can be used as valid alternative.
